Enum part of definition

- size16: A (enum) 
    - D
    - E

    - sample
        - F
        - G

    - default
        - H

Is converted into:

{
  "element": "enum",
  "attributes": {
    "samples": {
      "element": "array",
      "content": [
        {
          "element": "string",
          "content": "F"
        },
        {
          "element": "string",
          "content": "G"
        }
      ]
    },
    "enumerations": {
      "element": "array",
      "content": [
        {
          "element": "string",
          "content": "D"
        },
        {
          "element": "string",
          "content": "E"
        }
      ]
    },
    "default": {
      "element": "string",
      "content": "H"
    }
  },
  "content": {
    "element": "string",
    "content": "A"
  }
}

I'm not satisfied with, default and samples. For other cases there is in this attributes Element it self

e.g. for same definition of array instead of enum

{
  "element": "array",
  "attributes": {
    "samples": {
      "element": "array",
      "content": [
        {
          "element": "array",
          "content": [
            {
              "element": "string",
              "content": "F"
            },
            {
              "element": "string",
              "content": "G"
            }
          ]
        }
      ]
    },
    "default": {
      "element": "array",
      "content": [
        {
          "element": "string",
          "content": "H"
        }
      ]
    }
  },
  "content": [
    {
      "element": "string",
      "content": "A"
    },
    {
      "element": "string",
      "content": "D"
    },
    {
      "element": "string",
      "content": "E"
    }
  ]
}

So it is question, what should be result for enum To be consistent it has to be array of enum elements for samples and enum element for element.

There is question if sample should be more enums with individual values

{
  "element": "enum",
  "attributes": {
    "samples": {
      "element": "array",
      "content": [
        {
          "element" : "enum"
          "content" : {
            "element": "string",
            "content": "F"
          }
        },
        {
          "element" : "enum"
          "content" : {
            "element": "string",
            "content": "G"
          }
        },
      ]
    },
    "enumerations": {
      "element": "array",
      "content": [
        {
          "element": "string",
          "content": "D"
        },
        {
          "element": "string",
          "content": "E"
        }
      ]
    },
    "default": {
      "element": "enum",
      "content": {
        "element": "string",
        "content": "H"
      }
    }
  },
  "content": {
    "element": "string",
    "content": "A"
  }
}

Or one enum with attribute enumerations

{
  "element": "enum",
  "attributes": {
    "samples": {
      "element": "array",
      "content": [
        {
          "element": "enum",
          "attributes" : {
            "enumerations": {
              "element": "array",
              "content": [
                {
                  "element": "string",
                  "content": "D"
                },
                {
                  "element": "string",
                  "content": "E"
                }
              ]
            }
          }
        }
      ]
    },
    "enumerations": {
      "element": "array",
      "content": [
        {
          "element": "string",
          "content": "D"
        },
        {
          "element": "string",
          "content": "E"
        }
      ]
    },
    "default": {
      "element": "enum",
      "content": {
        "element": "string",
        "content": "H"
    }
  },
  "content": {
    "element": "string",
    "content": "A"
  }
}
